Fix several bugs in photochemistry related to the submit-crash-resubmit
problem: Some of the integers in the related routines are not set in
privatethreads. Consequently, the additives such as n=n+1 are accumulated with
threads, causing systermatic problems in the routine. This update fixed the
submit-crash-resubmit problem. The simulated results are same with previous
simulations as tested.
